Environment is a crucial element for yourself, the people around you, and human being all over the world. Recently environment issue has been a hot-bill. Some people hold the view that human activities do great damage to the globe, while others reckon that the earth has been better due to the activities. In my point of view, it is the behaviours that attribute to the exacerbation of the globe environment.



Firstly, the natural resource is dwindling day by day due to the activity of human being. Human is an greedy animal. More and more buildings are construct and forests become less and less. More and more fuels are needed to meet a requirement of increasing number of cars and petroleum and coal mines are become less and less. Some nature resources are used up by us so quickly which are formed more than millions of years. Thus, we are now confront a situation lacking of water and fuels. If we cannot recognize the seriousness of the problem, we will finally lose the suitable environment for our living.



Secondly, some serious environment problems have threaten our lives. For example, a  factory located nearby our university.  Everyday we are enveloped by smoke which released by the factory and the dirty water has made the river nearby be not as translucent as it was. Some other problems, such as global warming, breakage of ozone layer, are all owing to the human need and activities.



Thirdly, it is human activities that made the decrease in species, or even extinction. The habitant has been destroyed and the slaughter has been more and more frequent. For example, large numbers of Manchurian tiger once lived in the broad northeast of China, but now eighty percent of them have been died due to all kinds of factor related to the human activities. Manchurian tiger  is a kind of normal mammals when I was a child, but now it is under the threat of extinct.



From what has been discussed above, we know what we do to to the environment. We should be aware of the  hazard and take proper action, which make our earth more beautiful and harmonious.
